@Jimmy Ready The Pro membership of rentometer has a more detail summary of the comps by property type and addresses included. 

I only need to look into each city in greater detail of course. 

I would look at your contract with the contractor to see if there is any clause or details regarding change orders.

It would be nice to share ideas.A few more specifics: - I’m interested in single-family or small multi-family dwellings in A or B zones- The closer to the West Coast the better, but that said, I’d be willing to go all the way to Nova Scotia if that’s where the math works best...ideally I’d like to follow the one percent rule - Random detail: I’m actually a poet looking to support my writing habit through sound investing.

One added detail is this other couple are family (my husband's sister) so we need everything written and laid out clearly but with the assumption we will operate within these boundaries without going to court...meaning we don't need every word to be air tight but need it to be clear cut (as a side note I'm not interested in hearing about horror stories of doing business with family, I have done real estate business with family for over ten years and am fine with it). 

I have a few questions in how to start the offer/negotiation and listed the basic details of the property below.How would you structure a seller-financed deal?

Based on the details above, we would love to understand people's point of views on if this is a good deal or not and/or something that we should undertake. 

Your question is just too broad to get a more detail answer IMHO. 

Shoot me an email with some more details.

If I waited until end of 2019, I could afford more.I will message you for the lender's details.
